description/ordering information
The SN74CBTD3305C is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron),
allowing for minimal propagation delay. This device features an integrated diode in series with VCC to provide
level shifting for 5-V input down to 3.3-V output levels. Active Undershoot-Protection Circuitry on the A and B
ports of the SN74CBTD3305C provides protection for undershoot up to 2 V by sensing an undershoot event
and ensuring that the switch remains in the proper OFF state.
The SN74CBTD3305C is organized as two 1-bit bus switches with separate output-enable (1OE, 2OE) inputs.
It can be used as two 1-bit bus switches or as one 2-bit bus switch. When OE is high, the associated 1-bit bus
switch is ON, and the A port is connected to the B port, allowing bidirectional data flow between ports. When
OE is low, the associated 1-bit bus switch is OFF, and a high-impedance state exists between the A and B ports.
